* firewire: fw-ohci: unify printk prefixesStefan Richter2008-06-191-53/+48
| | | | | | | | | The messages which can be enabled by fw-ohci's debug module parameter are changed from KERN_DEBUG to KERN_NOTICE level and uniformly prefixed with "firewire_ohci: ". This further simplifies communication with users when we ask them to capture debug messages. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: fill_bus_reset_event needs lock protectionStefan Richter2008-06-191-2/+7
| | | | | | | | | | | | | | | | | | | | | Callers of fill_bus_reset_event() have to take card->lock. Otherwise access to node data may oops if node removal is in progress. A lockless alternative would be - event->local_node_id = card->local_node->node_id; + tmp = fw_node_get(card->local_node); + event->local_node_id = tmp->node_id; + fw_node_put(tmp); and ditto with the other node pointers which fill_bus_reset_event() accesses. But I went the locked route because one of the two callers already holds the lock. As a bonus, we don't need the memory barrier anymore because device->generation and device->node_id are written in a card->lock protected section.

* firewire: fw-ohci: write selfIDBufferPtr before LinkControl.rcvSelfIDStefan Richter2008-06-191-1/+1
| | | | | | | | | | | | | OHCI 1.1 clause 5.10 requires that selfIDBufferPtr is valid when a 1 is written into LinkControl.rcvSelfID. This driver bug has so far not been known to cause harm because most chips obviously accept a later selfIDBufferPtr write, at least before HCControl.linkEnable is written.

* firewire: fw-ohci: disable PHY packet reception into AR contextStefan Richter2008-06-191-0/+2
| | | | | | | | | | | | | We want the rcvPhyPkt bit in LinkControl off before we start using the chip. However, the spec says that the reset value of it is undefined. Hence switch it explicitly off. https://bugzilla.redhat.com/show_bug.cgi?id=244576#c48 shows that for example the nForce2 integrated FireWire controller seems to have it on by default.

* firewire: fw-ohci: use of uninitialized data in AR handlerStefan Richter2008-06-191-0/+5
| | | | | | | | | | | | header_length and payload_length are filled with random data if an unknown tcode was read from the AR buffer (i.e. if the AR buffer contained invalid data). We still need a better strategy to recover from this, but at least handle_ar_packet now doesn't return out of bound buffer addresses anymore. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: don't panic on invalid AR request bufferStefan Richter2008-06-191-1/+2
| | | | | | | | | | | BUG() at this place is wrong. (Unless if the low level driver would already do higher-level input validation of incoming request headers.) Invalid incoming requests or bugs in the controller which corrupt the AR-req buffer needlessly crashed the box because this is run in tasklet context.

* | x86-64: Fix "bytes left to copy" return value for copy_from_user()Linus Torvalds2008-06-172-28/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most users by far do not care about the exact return value (they only really care about whether the copy succeeded in its entirety or not), but a few special core routines actually care deeply about exactly how many bytes were copied from user space. And the unrolled versions of the x86-64 user copy routines would sometimes report that it had copied more bytes than it actually had. Very few uses actually have partial copies to begin with, but to make this bug even harder to trigger, most x86 CPU's use the "rep string" instructions for normal user copies, and that version didn't have this issue. To make it even harder to hit, the one user of this that really cared about the return value (and used the uncached version of the copy that doesn't use the "rep string" instructions) was the generic write routine, which pre-populated its source, once more hiding the problem by avoiding the exception case that triggers the bug. In other words, very special thanks to Bron Gondwana who not only triggered this, but created a test-program to show it, and bisected the behavior down to commit 08291429cfa6258c4cd95d8833beb40f828b194e ("mm: fix pagecache write deadlocks") which changed the access pattern just enough that you can now trigger it with 'writev()' with multiple iovec's. That commit itself was not the cause of the bug, it just allowed all the stars to align just right that you could trigger the problem. [ Side note: this is just the minimal fix to make the copy routines (with __copy_from_user_inatomic_nocache as the particular version that was involved in showing this) have the right return values. We really should improve on the exceptional case further - to make the copy do a byte-accurate copy up to the exact page limit that causes it to fail. As it is, the callers have to do extra work to handle the limit case gracefully. ] Reported-by: Bron Gondwana <brong@fastmail.fm> Cc: Nick Piggin <npiggin@suse.de> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Andi Kleen <andi@firstfloor.org> Cc: Al Viro <viro@ZenIV.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> (which didn't have this problem), and since most users that do the carethis was very hard to trigger, but

The old implementation schedules a timer interrupt for itself in the future by getting the current value of the Interval Timer Counter + 1000 cycles, waits for the interrupt to be pended, calls SAL_CACHE_FLUSH, and finally checks to see if the interrupt is still pending. This implementation can cause problems for virtual machine code if the process of scheduling the timer interrupt takes more than 1000 cycles; the virtual machine can end up sleeping for several hundred years while waiting for the ITC to wrap around. The fix is to use platform_send_ipi. The processor will still send an interrupt to itself, using the IA64_IPI_DM_INT delivery mode, which causes the IPI to look like an external interrupt. The rest of the SAL_CACHE_FLUSH + checking to see if the interrupt is still pending remains unchanged. This fix has been boot tested successfully on: - intel tiger2 - hp rx6600 - hp rx5670 The rx5670 has known buggy firmware, where SAL_CACHE_FLUSH drops pending interrupts. A boot test on this machine showed this message on the console: SAL: SAL_CACHE_FLUSH drops interrupts; PAL_CACHE_FLUSH will be used instead Which proves that the self-inflicted IPI approach is viable. And as expected, the other tested platforms correctly did not display the warning. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

In some cases, the controlling thread detects the state of the spu as running, and goes back to sleep resulting in a hung application as the event is missed. This change detects the stop condition and re-generates the wakeup event after a context save. Signed-off-by: Luke Browning <lukebrowning@us.ibm.com> Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

Its possible to build the phylib as a module, however this breaks the board level fix ups because phy_read and phy_write are not available if we build as a module. So we unconditionally select PHYLIB to ensure its built into the kernel if we are building in MPC85xx MDS support. This was determined to be the easiest soultion even though it prevents the user from removing PHYLIB support if they decide they don't want it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
